Starting in 2012, Boyesen redesigned the classic Power Reed to better meet the performance requirements that are unique to Observed Trial. The new RC2 Series Trial-specific Power Reed now incorporates new beam petal designs that are more sensitive to Trial specific rider inputs.

MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION Each Boyesen Power Reed system is unique - tailor made to your machine's specific model, year and displacement.
Boyesen's patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. More valves equals more power by creating:

More Air FlowThe dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently.

More Air VelocityThe multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports.

More Overall PowerDual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband.

T2 EPOXYThe most durable materials. The most lifespan.
The RC2 Series Power Reeds now features category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel.

MS PLUS FLOW OPTIMIZATIONOne reed petal is NOT enough!
The reed petals in modern 2 stroke Observed Trial engines take an incredible amount of abuse! At peak RPM reed petals are opening and closing hundreds of times per second. Over time, a single reed loses its ability to regulate flow rates in proper proportions. This causes a loss of reed petal reaction and reduces the consistency of peak horsepower.

Boyesen's race-proven MS PLUS Optimization uses multi-staged reed petals to distribute the engine’s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to acheive peak horsepower AND durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPMs.
